Try something like this:

B2: =IF(A2<>A1,1,B1+1)
copy down as far as needed

Does that help?

in B1 put 1
in B2 put:
=IF(A2=A1,B1+1,1)
and copy down

Thanks that did the trick

in B1 put 1
in B2 put:
=IF(A2=A1,B1+1,1)
and copy down

if your series starts in A1, then B1 = 1 and B2 would be
=IF(A2=A1,B1+1,1)
